  • the invention belongs to the field of novel cigarette smoking sets, in particular to a smoking device for induction heating in a folded airway.
  • heating methods for HNB cigarettes include: contact electric heating, non-contact electric heating, charcoal heating, and the like.
  • Contact electric heating refers to the direct contact heating of cigarettes to obtain flue gas. It uses various forms of heating equipment such as tubes, needles or plates that are electrically heated to directly contact cigarettes or shredded tobacco, and the temperature is lower than the ignition point of the cigarettes. It directly touches and bakes cigarettes or tobacco, so that the aroma components and smoke-emitting components of tobacco are volatilized, so as to meet the smoking requirements of smokers.
  • the shredded tobacco that is in direct contact with the cigarette or the shredded tobacco can be fully baked, while the shredded tobacco that is slightly farther from the heating element cannot be fully baked, and the baking effect has a certain difference in the cross section of the cigarette circumference uniformity;
  • the heating appliance itself is small in size, and its own heat capacity is not high. Smokers need to have a certain heating waiting time before smoking. Because the heating element is in direct contact with the shredded tobacco, in order to ensure the heating effect of the tobacco part far away from the heating body, the surface temperature of the heating element is usually increased by 10-20 degrees higher than the optimal heating temperature to ensure the adequacy of heating. But at the same time, the problem is: after the tobacco in contact with the heating element is heated for several times, the cured tobacco substance will stick to the heating element, which will bring peculiar smell or heating difficulty to the subsequent smoking of cigarettes. .

Similarly, it is difficult to control the charcoal rod after it is ignited, and there is also a roasting of the shredded tobacco when it is not smoking. Moreover, the end of the charcoal rod is also in direct contact with or relatively close to the cut tobacco. Therefore, there are the following problems: there is also a phenomenon that a small amount of residual cut tobacco is directly roasted or even marginally roasted at the end of the burning charcoal rod.

Abstract

L'invention concerne un dispositif de génération de fumée pour un chauffage par induction dans un canal d'air pliable, appartenant au domaine des ensembles à fumer chauffant pour cigarettes. Le dispositif de génération de fumée comprend un tuyau d'entrée de cigarette (1), une bobine d'induction (3), une coupelle chauffante (5), un élément chauffant (6) et un corps d'étanchéité à conduction magnétique (7). Le tuyau d'entrée de cigarette (1) est disposé au niveau d'une extrémité supérieure du dispositif de génération de fumée et a une structure de tuyau creuse, une cavité interne est une cavité de mélange de gaz (1D), le diamètre de la cavité de mélange de gaz (1D) est supérieur à celui d'une cavité interne de la coupelle chauffante (5), et un espace est ménagé entre la paroi interne du tuyau d'entrée de cigarette (1) et une extrémité supérieure de la coupelle chauffante (5) et sert de canal d'admission d'air (1A). Dans le dispositif de génération de fumée, un pliage spatial pour raccourcir une longueur axiale spatiale est réalisé sur une structure "corps chauffant + cigarette" d'origine, de manière à réduire la longueur axiale d'une partie chauffante d'un ensemble à fumer. L'élément chauffant (6) dans le dispositif de génération de fumée est disposé dans un canal d'air, et le canal d'air est plié vers l'avant et vers l'arrière, de telle sorte que la longueur d'un canal d'écoulement d'air soit augmentée, et la longueur axiale du dispositif de génération de fumée est réduite.
